Little Langdale has been heavily mined and quarried over the last several hundred years particularly for
copper and
slate although there is little activity there at present. Workings in the vicinity include the extensive slate quarries at Hodge Close,
Tilberthwaite and the mines on the southern slopes of Wetherlam. A nearby mine at Hawk Rigg possibly dates from the
Elizabethan era and it was reported in 1709 that
iron ore was mined in the area. Slate mining particularly boomed in the area in the
Victorian Era after the introduction of
compressed air drills for making the blast holes, and continued until the introduction of high quality
bricks for building. The spoil heaps from these mines form large banks where
silver birch and
larch now grow.
Greenburn Mine Greenburn Mine (also known as New Coniston Mine), close to Greenburn Beck and the disused Greenburn reservoir, is 'widely regarded as the best preserved
copper mine in the Lake District.' The mine was mostly worked in the mid-19th century but may have been operated from the late 17th century. It closed in 1865 but later re-opened with activity possibly until 1940. The shafts of the mine reached a depth of below ground level. The mine workings featured the large Engine Shaft with winding and pumping gear powered by a 9.8 m
overshot wheel, various other shafts and
adits, a
spalling floor, a
crushing mill powered by a second water-wheel, an inclined
tramways and two
precipitation tanks. There are remains of buildings including a
smithy, office, two-storey accommodation block,
dry store & miners' changing house and explosives store. At least five copper
veins were mined The effect of the damburst is visible in sediment cores from the downstream Little Langdale Tarn. ==Blea Tarn==
